# Call Center Calls Analysis The top stacked bar chart shows the numbers of calls answered, abandoned, and overflowed out for the whole Call Center between the date and time range entered in the chart options panel. Calls are grouped into hour periods between the start and end times entered in the chart options panel. The bottom chart shows the averages for queue, ring, conversation (talk), and wrap-up time for the Call Center and the same date and time ranges as previously set up in the chart options panel. If you hover the mouse over a data series, tooltips will be displayed with additional data for the specific item. As with all thebar charts, individual data series can be turned off or on by clicking the series legend on the right side of the charts. Also, the data used to generate the charts can be exported into XSLX format by clicking the export icon at the bottom right of the chart tab. See Exporting Charts for details.
